Re: st: RE: Pseudo R2 for xtlogit

As Nick indicates, there are many versions of the pseudo-R2.
However, if mentioned without qualification (like in the standard
output from logit models), it refers
to the improvement in the log-likelihood accomplished by the model and can be
displayed after any model by typing:
display "pseudo R2=" (e(ll_0)-e(ll))/e(ll_0)

There is no such thing as "the" pseudo-R^2.
But you can concoct one of your own designing.
In an up-to-date Stata,
. search r-square
for information.
Incidentally, Carter Rees suggested
. search xtlogit postestimation
which is good advice in general, but,
it seems, not relevant for this particular
question (please correct me otherwise).
